Application filed April 25,

This invention relates to improvements in pump operating mechanlsm.

One of the objects of the present invention and readily placed in position and operatively connected with the pitman of the pump and 15 manually controlled for operating deep well pumps and the like, with means for increasing or decreasing the stroke of the pitman.

A further object of the present invention is the provision of pump operating mecha- 20 nism of the above type which includes a rack bar connected with the pitman and cooperating with a manually controlled gear segment, together with means for engaging the 25 engaging the same therefrom.

l/Vith the above and other objects in view, the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set 39 forth, pointed out in the claims and shown in the accompanying drawing wherein:

Figure 1 is a side elevation illustrating the application of my improved pump operating mechanism Figure 2 is a detailed section on the line 2-2 of Figure 1;

v Figure 3 is a detailed transverse'section on the line 33 of Figure 4; and

Figure 4 is detailed side elevation illustratmeans for moving the gear segment into and out of engagement with the rack bar.

Referring to the drawing, it will be noted that I have illustrated an ordinary type of pump, the body of which is generally indicated at 1. Cooperating with the pump body and mounted for reciprocating movement therein is a pitman 2. Attached to the upper end of the body 1, is a bracket 3 which 5 comprises two opposed members each having gear segment with the rack or readily dising a form of the invention with improved 1 1931, semi in), 532,769.

one end arranged upon oppositesides of the upperend' of the pump body" and clamped thereto by means of thelb'olts 4, 'The other ends of the opposed membersof the bracket 3 have attached thereto, .thespaced upright struts 5 and connected to the upper ends of thestruts 5 is a guide arm 6 adapted to embrace the upper end of the-pitman for guiding the same in its movement, and carryinga bearing roller '7 engaging the pitman to permit the same to ride freely through the outer end of the arm 6.

Attached to the pitman 2 is a rackbar 8 having a plurality of spaced teeth 9 oooperating with the teeth 10 on the gear. segment The gear segment 11 is pivotally mounted between the struts 5 and is supported by means of a pivot bolt 12. Formed integral with the body of the gear segment 11 is 'a' late'ral projecting arm 13 having spaced ears 14: at the outer end, said ears being apertured to-receive thepin 15 which detachably connects the upper end of the link 16 to the outer end of the arm 13. E i Arranged between the lower end of the struts 5 andpositionedbetween theouter end of the opposed members'of the bracket 3 is'the apertured head 17 of the'hand lever 18. The head 17 ispivotally mounted upon a collar 19 supported by the pivot bolt 20 which is also used for connecting the lowerendsfof'the struts 5to the bracket 8. I

The handle '18 is provided with an arcuate curved portion 21 which has a transverse opening 22' to receive the lower end of -the link 16. The lower end of link 16 is pivotally connected tothe arcuate portion of the handle by means of the pin 23.

It will be apparent from the above con struction, that by connecting the handle member 18' with the pitman 2, through the medium-ofthe gear segment 11 and the rack bar 8, it will not require as much leverage-as would be ordinarily required it the handle was connected direct to the pitman, and by adjusting the upper end of the link 16 in the spaced ears 14, the leverage can be lengthened or shortenedasrequired, 1 v ..'.f It will be noted that-the spacedearsjl l at the outer end of arm 13 are provided with spacedapertures, so that theouter end of link 16 can be connected to either set of the apertures for adjusting the movement of the arms 13.

In Figures 3 and 4, I have illustrated a slightly modified form of the invention wherein the gear segment 11 has its loody portion provided with a central opening 2 1 in which is arranged a cam roller 25, keyedto the cross shaft 26, the'rends*Uf'whichare mounted in thespaced struts 5'. One end of the shaft 26 has attached thereto a-crank arm 27, carrying a lateral projecting handle have hereunto set my hand at Omro, in the Winnebago and State of ,Wiscon-.

I In themain form of the invention,-thel1and lever 18 gmay be quickly and easily disconnected from the gear segment 11 by removing eitherpin 15 or pin23,-so thatithe direct connection between the hand lever and the gear segment-will be broken. n It willalso be noted that withthis typeof operating mecha :nism, the usual required lleverage for-operatmg the pitman 2 is considerably reduced, so
